Copilot now available in classic Outlook for Windows 10 and 11?

Hi.

I've noticed that the Copilot feature is now available in my classic Outlook app. However, I'm not sure how to get access to this feature. I've checked the settings and options, but I couldn't find any information on how to enable or configure Copilot.
I'd love to hear any suggestions or solutions on how to access this feature and make the most of it. Thank you.
